i Application filed January 3, 1882. (No model.)

v a citizen of the United States, and a resident of the city of St.Louis, in the State of Missouri, have. invented certain new and usefulImprovements in-Grain-Drills, -of which the following is-a specic'ation.

This invention consistsrst, in the provision, in a grain-drill, of theseed-box bottom arranged in slides, so as to be adjustable in a lateraldirection, in order to bring the feed-` openings in said bottom `more orless over the feeding-cylinders, to-regulate the amountv of graindischarged; second, in the provision,

on the side of the feed-cylinder housing, of a projecting rim forclosing the bottom of the feed-openings in seed-box bottom and preventthe escape of grain whenthe feed of the drill77 is changed, said rimbeing'of a similar diameter to that of1 the feeding-cylinder; third, `inthe provision, in connection with the chaindrum that raises thegrain-nukes out of the ground, of a lever arranged, loosely'around saiddrum, and provided with a spring-pawl which engages in the teeth of aratchet-wheel secured to the drum, the construction being such that saidoperating-lever can beswung up into a vertical position when required,so as not to be in the way ofthe operatorwhen working at the rear of thedrill; fourth, in the provision, in connection with cach alternate flukeand drag-bar, of a curved lever pivotedv at the forward end of themachine, and having connection. with an operating -lever within reach ofthe operator, the construction being such that the ilukes can be allowedto assume a zigzag 7?' position, or befdrawn straight,77 when desired,as'will hereinaftermore fully'ap'- pear; fifth, in certain details ofconstruction, aswill: hereinafter moreA fully appear.

lever and v,drum for raising and lowering they grain-dukes. Fig.`15 islatransverse section of the same; Fig. 16 is au enlarged detaillongitudinal section of the feed-cylinder,

tubular thimbles or axles c?, secured to the,

sides of the ldrill-fiume, as clearly indicated in the-drawings.

c is an overhanginglange on said thiinble, to prevent access of dirt tothe bearing of the axle.

The bottom A- of the seed-box is arranged to slide'laterally in theseed-box under cleats a, and upon the fiat surfaces on the housings rofthe` feed-cylinders E', (see Fig. 2,) the'a'djustm'ent beingaccomplished by a sliding plate, D, arranged in slides D', and having. acamslot, d, in which engages the pin d o n the bottom A, (see Figs. 5and 6,) the construction being such that a longitudinal movement of saidplate will impart alateral adjustment to the bottom A. v

d2 is thumb-nut for locking the plate D inits".

required adjustment.

Fare the feed-cylinders,haviug-seed-grooves;

around their periphery, as shown, which'are preferably parallel with theaxis. The cyliuders turn upon an annular flange, e', of the housing E,asshown, and through a square or ICYO other corner-shaped opening passesthe driving-shaft L, common to all the feed-cylinders. c are inturnedflanges on the housing, to prevent the access of grain or dirt betweenthe ends of the feed-cylinder and the faces of said housing.

e2 is a circular fiange or' extension of the housing E, of a diameterequal to that of the feed-cylinder, the purpose oi' which is to close upthe bottom of the feed-openings a/ in the seed-box bottom A when saidbottom is adj usted in a lateral direction past the feed-cylinder inadjusting the feedf'7 ofthe drill. In each of the feed-openings a thereis arranged a hinged plate or gate, G, which, when in its down position,as shown in full lines in Figs. 2 and 1G, rests against the periphery ofthe feed-cylinder, so as to limit the feed of said cylinder to theamount of grain contained in iis seed-grooves. The gates are used intheir down position in sowing wheat; but when the drill is used forsowing oats they `will be turned up into the position indicated indotted lines in Figs. 2 and 11i, so as to leave a largedischarge-opening at the front ot' the housing E.

H are tunnels or receivers for receiving the grain discharged by theiced-cylinders, pivoted to ear-lugs It of the housing, as shown, andhaving hinge-joint connections at h with the conductors H, that conveythe grain to the ilukes I. The grain-dukes I are. connected by drag-barsI Il to the frame of the drill in the following manner: Each alternatebar l is connected to a xed pivot, fi, and the remaining bars I2 havetheir ends passed through stirrupeyes 41", with a pin, fi", to limittheir backward movement when in a zigzag position.

These last set of drag-bars I`',with their linkes, are drawn straight orinto line by the following means:

J is a hand-lever,pivoted at the rear of the drill, and having linkconnection j with a curved lever, J', the lower end of which engages apin-projection on each of said dragbars, so that by operating thehand-lever J the drag-ba1s,with their 1inkes,will be drawn forward intoline, and held in such position by a lateh,j, engaging apin on thehandlever J, to lock itin its up position.

The mechanism for turning the chain-drum K, so as to raise and lower thedrill-dukes, consists of a ratchet-wheel, k, fixed on said drum, and alever, K, loosely pivoted on the same, and provided with a spring-dogthat engages the ratchet-wheel when it is required to operatethechain-drum. The object of this construction is to permit ot' said leverbeing swung into av vertical position out of the way of the operatorworking at lthe rear of the drill.

k is a catch for holding the lever in its up position.

A supporting-braeket is arranged at the center of the chain-drum K, soas to support it at such point and prevent warping, and at the same timeform a pivot for the lever J.

The driving shalt or rod that operates the feeding-cylinders l isarranged to extend axially through the hubs ofthe driving-wheels, and isdivided into two sections, L L. section L is common to all thefeed-cylinders, and is capable of a rotation independent of thedriving-wheel C, through which it passes. The section L" is {ixed to thehub-cap L by a linchpin. I, and also byits squared portion passingthrough asimilar-shaped orifice in the cap, the said cap in turn beingsecured to the hub Gi by lugs l and recesses Z2, (see Fie'. 9,) so as torotate with the same. The positive motion imparted by the driving-wheelC to this shaft-section is imparted to the section L, that drives thei'ecding-cylinders, by means of a ratchet-clutch, M, in manner indicatedin Fig. 7. This ratchet clutch, in addition to permitting a retrogrademovement of the driving wheel without imparting a corresponding movementto the ieeding-cylinders, also permits of the employment ot' a cam, X,upon the oliaiirdrum K, so that when said drum is operated to li ft thegrain-linkes out of the ground the cam l\" will, through the operatingbell-crank fu, open the ratchet-clutch )I automatically, in order toprevent any further movement being imparted to the feedingeylinders. nis a spring for holding the clutch members in engagement. Theshaft-section Lis detachable endwise from the drill, so as to permit ofthe ready removal and replacement of the grain-feeding mechanism, and itis held in place in the drill by an abutmentcollar, O, and set-screw o,so that when the set-screw is loosened the shaft can be drawn outthrough the tubular axle of the drivingwheel C.

I is a cam formed on the collar O for the purpose of driving a suitablefeeding device in using the drill for sowing grass-seed.

The peculiar construction ofthe clutch M is as follows: m is a sleevesecured to the section L by a pin or rivet, m", and having aninelosing-sleeve over its ratchet face, as shown. This ratchet-face mayhave one or more ratchet-projections, as desired. m"7 is aslidingr'atchet-eollar having a square bore fitting over the squareshaft-section L, and imparting motion to same when the clutch parts arein engagement. The bearing plate or socket m for the sleeve m is letinto the side of the drill-timbers, in manner indicated in Fig. 7

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is
